Embodiment 1

[0033] like figure 1 and figure 2 As shown, a device for heating with flue gas includes a hot water tank 1, a combustion stove 6, and a flue gas pipe 5 for exhausting smoke from the combustion stove, and also includes a heat-conducting oil pipe 2 for containing heat-conducting oil. The oil pipe 2 is an annular pipeline, and the heat-conducting oil pipe 2 passes through the hot water tank 1 and the flue gas pipe 5;

[0034] The wall of the hot water tank 1 is provided with two holes for the heat conduction oil pipe 2 to enter and exit the heat water tank 1 respectively. Both are provided with external threads, and also include four nuts 7 and four gaskets 8, the heat conduction oil pipes 2 on both sides of the two holes are threaded with a nut 7, and the four gaskets 8 are respectively located on each nut. 7 and the wall surface of the hot water tank 1, during the rotation of each nut 7, each gasket 8 can be clamped between the end surface of the corresponding nut 7 and the ...

Embodiment 2

[0042] like figure 1 and figure 2 As shown, this embodiment is further limited on the basis of Embodiment 1: it also includes at least two expansion joints 3, the expansion joints 3 are connected in series on the heat transfer oil pipe 2, and the heat transfer oil pipe 2 inside the hot water tank 1, the heat transfer At least one expansion joint 3 is arranged on the heat conduction oil pipe 2 outside the water tank 1 . Since the heat-conducting oil pipe 2 has two states of cold state and hot state during use, the expansion joint 3 provided in the device can effectively reduce the thermal stress generated on the heat-conducting oil pipe 2 during use.

[0043] Since the hot water tank 1 is equivalent to an internal pressure container when it is connected to the water pipe network, in order to make the hot water tank 1 have better pressure resistance, the hot water tank 1 includes a cylindrical body and fixed The heads at different ends of the cylinder body are hemispherical h...

Abstract

The invention discloses a device using smoke for heating. The device using smoke for heating comprises a hot water tank, a combustion stove and a smoke pipe used for smoke discharging of the combustion stove. The device using smoke for heating further comprises a conduction oil pipe used for containing conduction oil. The conduction oil pipe is an annular pipeline and passes through the hot water tank and the smoke pipe. The conduction oil pipe is connected with the wall surface of the hot water tank through nuts. The device using smoke for heating further comprises a circulating pump used for driving the conduction oil in the conduction oil pipe to flow circularly. The device using smoke for heating further comprises an oil storage tank connected with the conduction oil pipe through a pipeline. By the adoption of the device, the problem that when straw is used as a heat source to heat water, the heated surface of water is prone to scaling can be solved; and meanwhile, the device is long in service life and high in heat transfer efficiency.

Description

technical field [0001] The invention relates to the technical field of fluid heating equipment, in particular to a heating device using flue gas. Background technique [0002] Hot water is an indispensable domestic water in people's daily life. In the prior art, gas-fired water heaters, electric water heaters, and solar water heaters all provide quick ways to obtain hot water. [0003] Nowadays, the combustion technology of crop stalks and tree branches has been developed, and the following combustion technology has appeared in the existing technology: put the straw and branches into the primary fuel chamber for combustion, and control the air intake volume of the primary fuel chamber , so that the flue gas exhausted from the primary fuel chamber contains a large amount of combustible gas, and the above combustible gas is used for the next combustion. In this way, less harmful substances are produced due to the combustion of combustible gas, which makes this combustion techn...
